y The present invention relates to an embossing machine and more particularly to a device of this character which is especially designed for use in the art of making relief maps and has for its primary object to provide, in a manner as hereinafter set forth, a machine embodying a novel construction, combination and arrangement of parts whereby a sheet of ductile material, such as 1 metal, may be worked or upset 1n a manner to rapidly form the desired reliefs thereon. Another important object of the invention is to provide an embossing machine of the aforementioned character, embodying a power driven reciprocating hammer having novel supporting means throu h the medium of which the hammer may rately moved over the work as desired.

Other ob'ects of the invention are to provide an em ossing machine of the character described which will be simple in construction, strong, durable, eflicient and reliable in operation and 'which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will becomeapparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and 'wherein:

Figure 1 is a view in side elevation of a machine in accordance with this invention. Figure 2 is a view in top plan thereof. Figure 3 is a view in vertical section taken substantially on the line 33 of Figure 1.

Figure 6 is a plan view of a sheet having thereon an outline to be embossed.

Figure 7 is a detail view in vertical section through the support' caster.

Referring now to t e drawings in. detail, it will be seen that the machine constituting the present invention comprises a base 1 from easily and accu- Figure 5 is a fragmentary detail viewinv 1931. Serial No. 543,926.

,A vertical pin 10 is rigidly mounted on the 1 base 1 forwardly of the'standard 2 and constitutes means or operatively connecting a lazytong 11 to the base, a spacing sleeve 12 being provided on'the pin 10 for supporting that end of the lazytong in elevated position. The lazytong 11 is operable in a horizontal plane.

directed upper end portion portion of the i The referencenumeral 13 designates a slab of suitable compressible material upon which theductile work sheet 14: is mounted and temporarily secured by suitable means. The usual drain 15 is disposed on one of the marginal portions of the sheet 14.

A11 elongated, horizontally disposed metallic plate 16 is pivot'ally mounted, at an intermediate point, on the outer end of the lazytong 11 and anchored in the rear ortion of said plate and depending there rom is a supporting caster which comprises a pivot pin 17 having a reduced lower end portion. upon which is rotatably mounted a substantially U-shaped bracket 18 which is hori zontally dis osed, the lower arm of said bracket .18 being comparatively long and bifurcated and having. journaled' thereon a roller 19 for travel on the element 15.

An electric motor 20 is mounted on the rear end portion of the plate 16. A cable 21 is trained over the pulley wheel 8 and has one end connected to the electric motor 20. A counterweight 22 is connected to the other end of the cable 21. Supporting cables 23 have-their lower ends connected to the side joints of the links of the lazytong and their upper ends connected by yokes 24 to the rotatable blocks 5.

.3 cngageable with the upper end of the head 27 for securing said head in adjusted position. If desired, the lower end portion of the shank 26 may be suitably scaled to facilitate adjusting the head 27 to a predetermined position. A coil spring 29 encircles the shank 26 and has one end engaged with a cross pin 30 which extends through the shank. The other end of the coil spring 29 is engaged with the plate 16. The coil spring 29 provides means, as will be ap-.

parent, for returning the hammer to its raised or inoperative position.

A shaft 31 is journaled in the upper end portion of the bracket 25 and mounted thereon for rotation therewith is a cam 32 which is operatively engageable with the upper end of the shank 26in the manner illustrated to advantage in Figure 3 of the drawings for depressing the hammer against the tension of the coll spring 29. The cam 32 may be secured in position on the shaft 31 by suitable means, such as a set screw 33. The shaft 31 is operatively connected to the electric motor 20 for actuation thereby through the medium of a train of reduction gears 34. A counterweight 35 is fixed on one end portion of the shaft 31.

Arms 36 are fixed on the rear end portion of the plate 16 and extend diagonally therefrom over the adjacent links of the lazytong 11. Said arms rest on the lazytong links and are slidable thereon to permit the operation of the lazytong. The arms 36 provide means for supporting the rear end portion of the plate 16 upon which the electric motor 20 is disposed. Handles 37 project laterally from the forward end portion of the plate 16, said forward end portion being tapered, as seen in Figure 2 of the drawings. It may be well to here call attention to the fact that the lowermost of the lazytong links with which the arms 36 are slidably engaged is provided with a raised thickened portion 38 which is flush with the u per surface of the other ofsaid lazytong links in order that "both-of the arms 36 will be. supported in the same horizontal plane.

In use, the sheet 14 is positioned on the I com ressible slab 13 and disposed beneath the ammer of the machine. The head 27 extends adjusted to the desired position on the shank 26 and the hammer is then reciprocated by energizing the electric motor 20. As before stated, the work is previously outlined on the sheet 14 and the hammer is then directed over the sheet as desired to form the reliefs designating the lowest elevations. The head 27 is then adjusted downwardly on the shank 26 to form the next lowest elevations on the sheet and this operation is re eated as many times as desired or as may e necessary. The sup orting structure for the hammer is such that the same may be directed over the work with a minimum of efi'ort. If desired, the supporting caster comprising the elements 17, 18 and 19 may be dispensed with and the reliefs designating different elevations formed in any desired order.

It is believed that the many advantages of amachine constructed in accordance with the present invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.
